Abstract (en)
In a direct forward throw sweeper (10), improvements related to a door (18) for closing the opening (16) into the hopper (12) permit backing away from a debris receptacle with the hopper door (18) open after dumping a load of debris without damage to the machine (10). Means (62,64) are provided for connecting a vacuum pickup wand to the debris hopper (12). Associated improvements to a related air filter chamber (86) provide improved dust control while dumping the hopper (12) and convenient access (90) for servicing a dust accumulation space in the bottom of the filter chamber (86). <IMAGE>
